CARRIAGE-SEAT.

SPECIFICATION formingpart of Letters Patent No. 274,131, dated March 20, 1883.

To all whom it may concern:

Application filed January 8, 1883. (No model.)

be inserted under and to hold against the hold- Be it known that I, FRANK DAVID Moing-bar D, provided with the bearing ends 0,

DoWELL,of Clinton, in the county of Clinton and State of Iowa, have invented certain new and useful Improvements in Carriage-Seats; and 'Ido hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to spring-backs for V6- hicle-seats, the object of the invention being to ease the back from the sudden jar caused in riding over rough, uneven places; and the invention consists of a seat-back attached to springsupports, removably connected with the seat, as hereinafter fully described.

Figure 1 is a perspective view of a seat having my improvements attached. Fig. 2 is a vertical section through one ofthe spring-supports. Fig. 3 is a plan of one of the devices bvwhich the spring-supports are held. Fig. 4 is an enlarged sectional view on line or a; of

Fig. 3 Fig. 5 is a side view of one of the hold-.

ing devices detached. I

A A represent the spring-supports, to the upper portion of which the back B is attached. The spring-plates are bent at b b, forming the base parts 0 0, which are made thinner than the supports A, and these base parts are adapted to rest upon the bottom of the seat (3, so as to be covered with the seat-cushion. The forward portion of these parts a are narrowed, forming shoulders at d, and the'ends are curved upward, forming the hooksb, to

having holes to receive the screws by which the bar is fastened to the seat.

To adjust the back in place it is elevated so as to place the parts a in position shown in dotted lines in Fig. 2, and the hooked ends I) are inserted under the holding-bar D, and, the back being then lowered,the parts 0 rest on the seat, and the hooks b and the shoulders (I hold the spring-supports in place. To remove the seat-back it is again elevated in position to allow the hooks to be withdrawn from under the holding-bar.

The spring-supports may be made of any suitable elastic materialpreferably of the best spring-steel, and, being the proper size to give the requisite spring to the back, it is evident it will be relieved of the sudden jar caused to backs without springs in riding over rough, uneven places.

What I claim as new, and desire to secure by Letters Patent, is

The combination, with the back B, attached to the spring-supports A A, having the parts 0 and the hooked ends I), of the holding-bar D, fastened to the seat U in position to receive and hold in place the spring-supports, substantially as and for the purposes described.

In testimony that I claim the toregoing as my own I affix my signature in presence ct tw witnesses.

FRANK DAVID MCDOWELL.
